Yes, I ran into the same problem with my E7250, using a netinst image and a live image. When trying to boot the live image I noticed these messages on the console: usb 1-2: device descriptor read/64, error -110 ... usb 1-2: reset high-speed USB device number 2 using xhci_hcd I tried booting from a different USB port; that worked once, but on a subsequent attempt it failed with the same issue. I did eventually get Debian installed, using a convoluted process that I won't describe here because I suspect it's not relevant (see below). I'm afraid that once I got Debian installed, I never went back to figure out what was causing the earlier failures. After reading your posting, I tried again to create a live USB stick. I used cp to copy the image to /dev/sdb, and I ran sync afterwards. Same failure. I then tried using dd instead of cp, and I used a different USB port on my desktop to write to the USB stick. This time I could boot the live image. I checked kern.log, and it had usb 2-2: device descriptor read/64, error -110 but did not have the "reset" message. (And I notice that this time it's "usb 2-2" rather than "usb 1-2".) I tried to boot off the USB stick a second time, and this time I got the failure again. So I suspect the problem has to do with peculiarities of the E7250, rather than issues writing the USB stick. I have a copy of kern.log from the first (successful) boot, and I have the dmesg output from the second (failed) boot. If anyone wants to look at them, let me know. mike
